Description

Electric instant hot water heater {Electric type hot water heater}

The present invention relates to an electric instantaneous hot water device that can be used to quickly heat the fluid to the desired temperature and at the same time can also function as a boiler, and to minimize the consumption of electrical energy for heating the fluid. will be.

Generally, instantaneous hot water device has various kinds according to its capacity or heating method. In case of small size, that is, relatively small capacity that is applied to bidet, etc., heating fluid is installed by using heating means directly in the waterway. Use a fluid to heat the burner.

In the conventional instant hot water device, as shown in FIG. 1, the cylindrical housing 110 is supplied with water therein, the discharge pipe 102 communicating with the housing 110, and the water introduced and introduced into the housing 110. The heater 130 is heated, the cap 120 to cover one end of the housing 110, and the drainage means 150 mounted on the cap 120 to discharge the remaining water in the housing 110 is large.

Here, the packing member 151 having the hole 151a is mounted inside the cap 120, and a disc is formed to open and close the hole 151a of the packing member 151, and is pressed into the cap 120. The valve 152 is installed. Here, one end of the push valve 152 penetrates through the hole 121 of the cap 120 and is exposed to the outside, and the other end is mounted in the form of being fitted into the hole of the guide member 154 installed inside the housing 110. Here, the elastic spring 153 is interposed between the guide member 154 and the disc.

Although not shown in the drawings, a control unit equipped with a heating control unit for controlling driving of the heater 130 is configured separately from the housing 110, and a heat dissipating unit such as a heat sink is installed to cool the control unit and the heating control unit.

Referring to the operation of the conventional instantaneous hot water device 100 through the configuration as described above are as follows.

When the heater 130 is driven through the control unit while the water is supplied into the heater 130 through the water supply, the water passing through the heater 130 is increased in temperature and discharged through the discharge pipe 102.

At this time, it is possible to prevent the leakage of hot water in a state that the disc of the pressing valve 152 is sealed in the hole 151a of the packing member 151 mounted at one end of the housing 110.

After exhausting the amount of hot water intended to go through this process, it is necessary to drain the remaining water remaining in the housing 110, which is pressed by one end of the push valve 152 exposed to the outside of the cap 120 packing member ( 151 and the disc of the push valve 152 is to be drained through the hole 121 of the cap 120.

In addition, this is to prevent the device 100 from being damaged by freezing during winter operation when water remains in the housing 100 after the instantaneous hot water device 100 is produced.

On the other hand, the elastic spring 153 interposed between the disc and the guide member 154 of the push valve 152 as described above is always exposed to hot water for the reason that is mounted inside the housing 110, or corroded in a long time use The elastic force is lowered so that the disc of the push valve 152 does not seal the packing member 151 smoothly. Therefore, hot water leaks through the holes 151a of the packing member 151.

In addition, there is a problem that the assembly cost is increased by mounting a number of parts, including the guide member 154 as described above.

In addition, when the hot water heated through the heater 130 is discharged to the discharge pipe 102 through the heater 130, the edge portion thereof does not smoothly discharge to the discharge pipe 102 due to the angled holes. There is this.

On the other hand, the control unit is manufactured separately from the housing 110, and the heat dissipation unit for cooling the heating control unit for controlling the heater 130 is added to the control unit has a problem that the cost rises and the size of the control unit increases.

On the other hand, the boiler is a device that generates heat energy using fuel and electricity such as oil and gas as energy sources, and generates heating water or hot water by heat exchange of heat energy and water. It is divided into boiler and electric boiler.

Combustion type boilers using fuels such as oil and gas as energy sources generate heat energy by burning fuel by a burner, and generate heating water by heat-exchanging water circulating pipes by operating heat energy and a pump. .

However, combustion boilers are expensive because many components are used for storing, supplying, burning, and exhausting fuel, and have a disadvantage in that productivity is greatly reduced due to a complicated structure. In addition, the combustion boiler should be equipped with a separate boiler room that is well ventilated and separated from the heating area in order to prevent the gas poisoning accident caused by the air supply and burnout of the exhaust gas required for burning the burner. The length of the pipe installed between the heating zone and the heating zone is complicated, so that there is a problem that the loss of thermal energy is large, the workability is greatly reduced.

In the case of gas boilers, gas poisoning and explosion accidents caused by gas leakage cause enormous loss of life and property, and thus, it is cumbersome and inconvenient to operate such as requiring periodic inspection of burners and pipes.

On the other hand, electric boilers have the advantage of easy installation and operation compared to combustion boilers because of the use of electricity as an energy source, there is a disadvantage that easily occurs, low energy efficiency.

In order to reduce the operation cost of the electric boiler, it is operated at midnight (22:00 to 08:00 the next day) when the electric charge is discounted, and generates and stores hot water at about 90 ℃, and the user uses the hot water at the required time. There is a variety of late-night regenerative electric boilers.

Representative of the various types of electric boilers as described above are shown in Figure 2, looking at the configuration as follows.

Will be heated.

In the conventional water heating method of this type, starting from the heating coil (5), since the water in the heating tube (7) → heat transfer medium (6) → closed tube (8) → water tank (2) must be heated sequentially As a result, rapid heating is not achieved, and there is a disadvantage in that a lot of heat is consumed and power is consumed. In addition, since the water heating of the water tank 2 heats and expands the area gradually from the part in contact with the surface of the closed tube 8 to the outside thereof, there is a problem of heat loss and rapidity, which is inferior. Energy) is consumed a lot.
